The hardest to fill role is that of senior data modeller, with two thirds (65%) of job vacancies left unfilled after 60 days. But even employers looking for less niche roles are finding recruitment hard; 56% of ads for senior programmers have not been filled in 60 days, despite a £45,000 salary. Organisations hunting for systems consultants will have to pay about the same and are also in for a long wait before finding a recruit. The top paying job on the list of hard-to-fill roles is that of principal software engineer at an average salary of £62,000.
According to Indeed, the top 10 hardest to fill tech jobs pay on average £47,460.
